Description

Technical Field

[0001] This application relates to the field of construction equipment, and in particular to a detachable and quick-assembly scaffolding. Background Technology

[0002] Scaffolding is widely used in high-altitude operations during the construction phase. The working platform erected by scaffolding can withstand a large load, thereby ensuring the smooth progress of the construction process. Scaffolding can be divided into different types according to its structural form, such as vertical pipe scaffolding, bridge scaffolding, portal scaffolding, and climbing scaffolding. Traditional scaffolding is usually fixed by welding, which is troublesome to transport and install. Therefore, detachable scaffolding has emerged.

[0003] The scaffolding of related technologies is usually made up of several steel pipes connected by couplers and stacked layer by layer to form a frame system. Since the steel pipes are all single pieces, the frame made of steel pipes needs to be equipped with couplers at each splicing node, which leads to an increase in the number of nodes in the scaffolding and can easily affect the efficiency of scaffolding construction. Utility Model Content

[0004] To address the issue of numerous scaffolding joints affecting construction efficiency, this application provides a detachable and quick-assembly scaffolding.

[0005] The detachable and quick-assembly scaffolding provided in this application adopts the following technical solution: A detachable and quick-assembly scaffold includes a base and upright frames. The upright frames are connected to the upper end of the base via a first plug-in assembly. Several upright frames are arranged and stacked sequentially on the base. Each pair of adjacent upright frames is connected via a second plug-in assembly.

[0006] By adopting the above technical solution, the base and each upright frame are an independent unit, reducing the number of connection nodes during scaffolding installation, making the scaffolding installation and dismantling of this application more efficient and saving construction time; the first insert rod connects the base and the first layer of upright frames, and the second insert rod stacks the upright frames layer by layer, allowing the scaffolding of this application to flexibly change its height according to actual construction needs, which is convenient for use.

[0007] Optionally, the first plug-in assembly includes a first plug rod, the two ends of which are plugged into the base and the upright frame respectively; the second plug-in assembly includes a second plug rod, the two ends of which are plugged into two adjacent upright frames above and below respectively.

[0008] By adopting the above technical solution, the first insert rod connects the base and the upright frame to form the first layer of the scaffolding, and the second insert rod connects the two adjacent upright frames to increase the height of the scaffolding. The first insert rod and the second insert rod are easy to use and improve the efficiency of scaffolding installation and dismantling.

[0009] Optionally, the frames are staggered and connected in their stacking direction, and the plane of each layer of frames is perpendicular to the plane of the two adjacent layers of frames.

[0010] By adopting the above technical solution, the staggered connection can reduce the swaying of the scaffolding when subjected to forces in different directions, enhance stability, and improve the safety of the scaffolding used in this application.

[0011] Optionally, the upright frame is connected to ribs at each corner.

[0012] By adopting the above technical solutions, the ribs can enhance the strength of the uprights, making them less prone to deformation or damage when bearing loads, thus enhancing the strength and stability of the scaffolding and making the construction process safer.

[0013] Optionally, a number of footboards are connected to the upright frame.

[0014] By adopting the above technical solution, the footboard facilitates workers' climbing when working at heights, and makes the construction process smoother.

[0015] Optionally, each layer of the uprights has two parallel uprights, and the two uprights on the same layer are connected by diagonal braces, which are connected to the uprights by connecting components.

[0016] By adopting the above technical solutions, the diagonal bracing can enhance the stability of the scaffolding under different directional forces and reduce the swaying of the scaffolding during use.

[0017] Optionally, the connecting component includes a scaffolding coupler, one end of which is connected to the upright frame and the other end of which is connected to the diagonal brace.

[0018] By adopting the above technical solution, the scaffolding coupler can fix the diagonal brace to the upright frame, thereby providing support for the two opposing upright frames and enhancing the stability of the scaffolding of this application. In addition, the scaffolding coupler can adjust the extension length and angle of the diagonal brace, so that the diagonal brace can be adapted to upright frames of different specifications, thus expanding the scope of application.

[0019] Optionally, the connecting assembly includes a first clamp, a second clamp, and a pin. The first clamp is connected to the diagonal brace, and the second clamp is connected to the vertical frame. The first clamp and the second clamp are respectively provided with a first ring and a second ring that match the pin. Both the first ring and the second ring are provided with magnetic pieces for attracting the pin. The pin is inclined to the horizontal plane, passes through the first ring and the second ring in sequence, and connects the diagonal brace to the vertical frame.

[0020] By adopting the above technical solution, the pin can fix the diagonal brace to the upright frame and play a supporting role for the upright frame. The inclined insertion of the pin and the ring make it difficult for the pin to fall off when the diagonal brace is subjected to lateral force. Combined with the adsorption effect of the magnetic sheet, the stability of the scaffolding installation and use is improved.

[0021] Optionally, the end of the base away from the upright frame is connected to a roller via a connecting rod. A sliding sleeve is connected to the connecting rod, and a threaded sleeve is rotatably connected to the sliding sleeve. The threaded sleeve is threadedly connected to the connecting rod. A support frame for supporting the base is connected to the sliding sleeve. A sliding plate is provided at the end of the support frame near the roller, and an anti-slip pad is provided at the end of the sliding plate away from the support frame. A wedge block is slidably connected to the sliding plate, and a through-hole is opened on the wedge block. A stud is provided on the sliding plate, and the stud passes through the through-hole and is threadedly connected to a first nut.

[0022] By adopting the above technical solutions, the rollers facilitate the movement of the scaffolding of this application and reduce the burden on workers to carry the scaffolding; the support frame can be raised and lowered and fixed by the screw sleeve, thereby controlling the contact between the sliding plate and the ground; the wedge block moves on the sliding plate to abut against the roller, which can limit the movement of the roller and thus fix the position of the scaffolding; the anti-slip pad increases the friction between the support frame and the ground, and improves the stability of the scaffolding of this application.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The upright frame serves as the smallest unit for scaffolding installation and dismantling, reducing the number of connection points in the scaffolding. The first insert rod connects the base to the upright frame, and the second insert rod connects two adjacent upright frames, enabling rapid assembly and dismantling of the scaffolding. 2. The ribs on the uprights increase the strength of the uprights. The uprights of each layer of the scaffolding are staggered with the adjacent two layers of uprights, which enhances the scaffolding's ability to resist forces in different directions. Combined with the support of the diagonal braces, it reduces the swaying of the scaffolding during use, enhances the stability of this application, and makes the construction process safer. 3. The rollers facilitate the movement of the scaffolding. The support frame can be lowered after the scaffolding is moved to a suitable position and work with the wedge block to block the movement of the rollers, thereby fixing the position of the scaffolding and improving the flexibility and stability of the scaffolding in this application.

[0033] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0034] Example 1: This application discloses a detachable and quick-assembly scaffolding, as described in the embodiments below. Figure 1 The system includes a base 1 and a vertical frame 2. The base 1 is a rectangular frame constructed from several steel pipes. The vertical frame 2 includes two vertical pipes 21 and two horizontal pipes 22. The two horizontal pipes 22 are fixedly connected to the two vertical pipes 21 at both ends, and the inner contour of the vertical frame 2 is rectangular. Ribs 5 are fixedly connected to the four apex corners of the rectangular inner contour of the vertical frame 2. One side of the rib 5 is fixed to the vertical pipe 21, and the other end is fixed to the horizontal pipe 22. Two footboards 6 are fixedly connected to one of the vertical pipes 21 of the vertical frame 2. Several vertical frames 2 are provided and stacked on the base 1 in sequence along the height direction of the base 1. There are two vertical frames 2 in each layer, and the two vertical frames 2 are parallel to each other. The vertical frames 2 in the upper and lower layers are staggered and their planes are perpendicular to each other.

[0035] like Figure 2 and Figure 3As shown, the bottommost frame 2 is connected to the base via a first insertion assembly 3, and the two adjacent frames 2 are connected via a second insertion assembly 4. The first insertion assembly 3 includes a first insertion rod 31, with each vertical pipe 21 in the frame 2 corresponding to a vertical steel pipe in the base 1. One end of the first insertion rod 31 is inserted into the vertical pipe, and the other end is inserted into the steel pipe of the base 1. The second insertion assembly 4 includes a second insertion rod 41, with each vertical pipe 21 in the two frames 2 corresponding to a vertical pipe. Both ends of the second insertion rod 41 are inserted into two opposite vertical pipes 21. The first insertion rod 31 and the second insertion rod 41 have the same specifications; both are stepped shafts divided into three sections, with the diameters at both ends smaller than the diameter of the middle section.

[0036] When connecting the base 1 and the upright frame 2, the operator first inserts the four first insert rods 31 into the base 1, and then inserts the first insert rods 31 on the base 1 into the four upright pipes 21 of the two upright frames 2, so that the two upright frames 2 are parallel and opposite to each other along the two long sides of the base 1, thus building the first layer of the scaffolding.

[0037] When connecting two adjacent vertical frames 2, the operator inserts one end of each of the four second insert rods 32 into the vertical pipe 21 of the lower vertical frame 2, and then inserts the other end of each of the four second insert rods 32 into the four vertical pipes 21 of the two upper vertical frames 2, so that the planes of the two adjacent vertical frames 2 are perpendicular to each other, and so on, until the scaffolding is increased to the height required for construction.

[0038] like Figure 1 As shown, the top layer of the scaffolding is connected to the top frame 20 via a second insert rod 41. The top frame 20 is a cuboid constructed from several steel pipes. The vertical pipes 21 in the topmost vertical frame 2 correspond one-to-one with the vertical steel pipes in the top frame 20. One end of the second insert rod 41 is inserted into the vertical pipe 21, and the other end is inserted into the steel pipe of the top frame 20. The top frame 20 is aligned with the bottom 1 to improve the overall strength of the scaffolding. When installing the top frame 20, the second insert rod 41 is inserted into the four vertical pipes 21 of the two topmost vertical frames 2, and the steel pipe of the top frame 20 is connected to the second insert rod 41.

[0039] like Figure 1 As shown, a diagonal brace 7 is connected in the three-dimensional space enclosed by two upright frames 2 on the same layer. One end of the diagonal brace 7 is connected to the horizontal tube 22 of one of the upright frames 2 near the base 1, and the other end is connected to the horizontal tube 22 of the other upright frame 2 away from the base 1. The diagonal brace 7 is supported on the horizontal tube 22 by the connecting component 8.

[0040] like Figure 2 and Figure 4As shown, the connecting component 8 includes scaffolding couplers 81. Each of the two vertical frames 2 of each layer is connected to a scaffolding coupler 81 on its horizontal tube 22. The two scaffolding couplers 81 are connected to the two ends of the diagonal brace 7, thereby supporting the diagonal brace 7 between the two vertical frames 2.

[0041] During installation, after each layer of scaffolding is erected, the operator must install diagonal braces 7 on the two horizontal pipes 22 that are staggered vertically on the two upright frames 2. The operator first connects the two scaffolding couplers 81 to the two horizontal pipes 22 respectively, and then adjusts the angle and position of the scaffolding couplers 81 on the horizontal pipes 22 according to the height difference between the horizontal pipes 22 and the required support angle. The two scaffolding couplers 81 are then connected to the two ends of the diagonal braces 7 to form support for the upright frames 2.

[0042] like Figure 5 As shown, the end of the base 1 away from the frame 2 is connected to a roller 10 via a connecting rod 9. A sliding sleeve 11 is slidably connected to the connecting rod 9, and a screw sleeve 12 is rotatably connected to the sliding sleeve 11. The screw sleeve 12 is threadedly connected to the connecting rod 9. A support frame 13 for fixing the position of the base 1 is fixedly connected to the sliding sleeve 11. A slide plate 14 is fixedly connected to the end of the support frame 13 near the roller 10. There are two slide plates 14, which are symmetrically distributed on both sides of the axis of the connecting rod 9. An anti-slip pad 15 is fixedly connected to the end of the slide plate 14 away from the base 1. A wedge block 16 is slidably connected to each of the two slide plates 14. The two wedge blocks 16 are located on both sides of the roller 10. A through waist-shaped hole 17 is opened on the wedge block 16. A stud 18 is fixedly connected to the slide plate 14. The stud 18 passes vertically upward through the waist-shaped hole 17 and is threadedly connected to a first nut 19. Tightening the first nut 19 will press the wedge block 16 against the slide plate 14.

[0043] In use, the operator first rotates the threaded sleeve 12 to move the sliding sleeve 11 upward, causing the support frame 13 to leave the ground. Then, the base 1 is moved to a suitable construction position using the rollers 10. The threaded sleeve 12 is rotated in the opposite direction to move the sliding sleeve 11 and the support frame 13 downward, allowing the anti-slip pad 15 at the bottom of the sliding plate 14 to abut against the ground. The wedge block 16 is moved on the sliding plate 14, inserted into the gap between the ground and the rollers 10, and the first nut 19 on the stud 18 is tightened to fix the position of the wedge block 16. This ensures that the rollers 10 are within the range limited by the two wedge blocks 16 and abut against them. Then, the scaffolding is installed. Alternatively, after the scaffolding is installed, the operator can move the scaffolding to a designated position using the rollers 10 and fix the position of the scaffolding using the support frame 13 and the wedge blocks 16.

[0044] Example 2: A detachable and quick-assembly scaffolding, which differs from Embodiment 1 in that, as Figure 6 and Figure 7As shown, the connecting assembly 8 includes a first clamp 82, a second clamp 83, and a pin 84. The first clamp 82 is slidably connected to the diagonal brace 7, and the second clamp 83 is slidably connected to the horizontal tube 22 of the vertical frame 2. Both the first clamp 82 and the second clamp 83 are fixed by bolts, with two bolts passing through the first clamp 82 and the second clamp 83 respectively and threaded with nuts. The pin 84 is L-shaped, and a first ring 85 and a second ring 86 matching the pin 84 are fixedly connected to the first clamp 82 and the second clamp 83 respectively.

[0045] like Figure 6 and Figure 8 As shown, magnetic sheets 87 for attracting pins 84 are fixedly connected inside the first ring 85 and the second ring 86. The pins 84 are inclined to the horizontal plane and pass through the first ring 85 and the second ring 86 in sequence, connecting the diagonal brace 7 to the horizontal tube 22 of the upright frame 2.

[0046] When installing the diagonal brace 7, the operator adjusts the extension length of the diagonal brace 7 in the first clamp 82 according to the required support angle and height. The diagonal brace 7 is then placed on the two vertically misaligned horizontal tubes 22 of the two vertical frames 2 on the same layer. The second clamp 83 is connected to the horizontal tube 22. The angles of the first ring 85 and the second ring 86 are adjusted so that the pin 84 can be inserted at an angle to the horizontal plane. Then, the first clamp 82 and the second clamp 83 are fixed respectively. The pin 84 is then inserted into the first ring 85 and the second ring 86 in sequence, so that the diagonal brace 7 is supported between the two vertical frames 2 on the same layer.

[0047] The implementation principle of this application embodiment is as follows: When installing scaffolding, the operator first rotates the screw sleeve 12 to move it upward, so that the sliding sleeve 11 drives the support frame 13 to move upward and leave the ground. After moving the base 1 to the designated position, the screw sleeve 12 is rotated in the opposite direction to lower the support frame 13, so that the slide plate 14 abuts against the ground. Then, the wedge block 16 on the slide plate 14 is moved so that the wedge block 16 abuts against the roller 10. The first nut 19 on the stud 18 is tightened to fix the position of the wedge block 16 on the slide plate 14, restricting the movement of the roller 10. Then, the scaffolding is installed.

[0048] The operator uses the vertical frame 2 as the smallest unit for scaffolding connection, inserting the two ends of the first insert rod 31 to the vertical pipe 21 and the base 1 of the vertical frame 2, respectively. The second insert rod 32 is used to install the vertical frames 2 on each layer of the scaffolding. Once the designated height is reached, the top frame 20 is connected via the second insert rod 32. The operator uses fasteners 71 or inclined pins 84 between the two vertical frames 2 on each layer to connect the diagonal brace 7 to the horizontal pipe 22 to provide support in different directions. The vertical frame 2, as the smallest unit for scaffolding installation, reduces the number of connection points. Combined with the first insert rod 31 and the second insert rod 41, it enables rapid installation and dismantling of the scaffolding. Simultaneously, the ribs 5 and diagonal braces 7 enhance the stability of the scaffolding under forces from different directions.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
